Notes
10.2. Precautions on electrical wiring work
■
Before obtaining access to terminal devices, all supply circuits
must be interrupted.
■
Use only copper wires.
■
Do not turn on the main switch until all the wiring is completed.
Make sure that the main switch has a contact separation of at
least 3 mm in all poles.
■
Never squeeze bundled cables into a unit.
■
Fix cables so that cables do not make contact with the pipes
(especially on high pressure side).
■
Secure the electrical wiring with clamping material as shown in
figure 12
so that it does not come in contact with the piping,
particularly on the high-pressure side.
Make sure no external pressure is applied to the terminal
connectors.
■
When installing the earth leakage breaker make sure that it is
compatible with the inverter (resistant to high frequency
electrical noise) to avoid unnecessary opening of the earth
leakage breaker.
■
As this unit is equipped with an inverter, installing a phase
advancing capacitor not only will deteriorate power factor
improvement effect, but also may cause capacitor abnormal
heating accident due to high-frequency waves. Therefore, never
install a phase advancing capacitor.
■
Follow the "electrical wiring diagram" when carrying out any
electrical wiring.
■
Always ground wires. (In accordance with national regulations of
the pertinent country.)
■
Do not connect the ground wire to gas pipes, sewage pipes,
lightning rods, or telephone ground wires.
•
Combustion gas pipes: can explode or catch fire if there is a
gas leak.
•
Sewage pipes: no grounding effect is possible if hard plastic
piping is used.
•
Telephone ground wires and lightning rods: dangerous when
struck by lightning due to abnormal rise in electrical potential
in the grounding.
■
This unit uses an inverter, and therefore generates noise, which
will have to be reduced to avoid interfering with other devices.
The outer casing of the product may take on an electrical charge
due to leaked electrical current, which will have to be discharged
with the grounding.
■
Only for Y1: Make sure to connect power supply cables in
normal phase. If connected in reverse phase, the remote
controller of the indoor unit indicates "
U1
" and the equipment
cannot operate. Change any two of the three power supply
cables (L1, L2, L3) to correct phase.
10.3. Connection example of total system wiring
For Sky Air or room air conditioner indoor units only: see
figure 9
For VRV indoor units only: see
figure 10
10.4. Connecting power wire and transmission wires
■
Let the power wire (including ground wire) go through the power
outlet port on either the front, side or back of the outdoor unit.
■
Let the transmission wires go through the cable outlet port, pipe
outlet port or knock-out hole on either the front, side or back of
the outdoor unit.
(See figure 12)
.
Precautions when knocking out knock-out holes
■
To punch a knock hole, hit on it with a hammer.
■
After knocking out the holes, we recommend you paint the
edges and areas around the edges using the repair paint to
prevent rusting.
■
When passing electrical wiring through the knock holes, remove
any burrs from the knock holes and wrap the wiring with
protective tape to prevent damage.
■
If there is any possibility that small animals enter the system
through the knock holes, plug the holes with packing materials
(to be prepared on-site).

This wiring diagram only applies to the outdoor unit.
4
When using the option adaptor, refer to the installation
manual.
5
Refer to the wiring diagram sticker (on the back of the front
plate) for instructions on how to use BS1~BS5 and DS1-1,
DS1-2 switches.
6
Do not operate the unit by short-circuiting protection device
S1PH.
8
For Sky Air or room air conditioner indoor units only:
Refer to the installation manual for connection wiring to BP
unit-outdoor transmission F1-F2.
9
For VRV indoor units only:
Refer to the installation manual for connection wiring to
indoor-outdoor transmission F1-F2.
10
When using the central control system, connect outdoor-
outdoor transmission F1-F2.
